APPARATUS FOR ORNAIVIENTING WOOD;

SPECIFICATION forming part of Letters Patent No. 773,855, dated.November 1, 1904.

Application filed May 5, 1904;. Serial No. 206,785. (No model.)

To all whom it may concern:

Be it known that we, TILLIAM W. DITTMAR, OLIVER F. DITTMAR, and ELMER O.DITTMAR, citizens of the United States, residing at Villiamsport, in thecounty of Lycoming, State of Pennsylvania, have invented certain new anduseful Improvements in Apparatus for Ornamenting Wood, of which thefollowing is a specification, reference being had therein IO to theaccompanying drawings.

This invention relates to an apparatus for ornamenting wood, andparticularly to a construction adapted to ornament simultaneously theentire surface of an article by compression thereof toward the radialcenter of the article.

The invention has for an object to provide dies or similar means forcompressing the entire periphery of the article at equidistant pointsboth radially and tangentially to the center of the Work, said means oftangential pressure extending parallel to the radial pressure andintersecting each other at such an angle as to produce a resultantradial pressure 2 5 toward the center, thus producing the effect of aradial compression upon the entire surface, and thereby preventing thesplitting of the material of the article at the sides thereof and alsopermitting the production of a design of equal depth upon all theperiphery thereof.

A further object of the invention is to provide an improved frame forsupporting the dies at an angle to each other whereby they may be geareddirectly together for the pur- 3 5 pose of producing a simultaneousmovement thereof in the same direction to feed the article between thedies while the ornamenting operation is being performed.

Another object of the invention is to pro- 4 vide an improvedconstruction of chuck for supporting and clamping the die in positionwhich will allow for a ready adjustmentnecessary in the use of dies ofdifferent sizes and can be operated by a suitable wrench withoutdisturbing any of the other elements of the machine.

Other and further objects and advantages of the invention will behereinafter set forth and the novel features thereof defined by theappended claims. 5

In the drawings, Figure 1 is a front elevation withp arts broken away;Fig. 2, a side view thereof; Fig. 3. an enlarged central section throughone of the dies and its operatinggears to illustrate the chuckconstruction; Fig. 4, an elevation of the work performed by the machine,and Fig. 5 a detail perspective of the chuck-ring.

Like letters of reference refer to like parts in the several figures ofthe drawings.

The frame of the machine may be of any desired construction suitable forthe purpose; but as illustrating a desirable form thereof we have shownthe frame as comprising a ring or annulus A, provided withsupporting-stand- 5 ards A at its base and with inwardly-projectingangular brackets A which may be formed integral with the frame orsuitably secured thereto to provide bearings for the die-rollers B, thejournals B of which are mounted in 7 these brackets. For the purpose ofdriving the die-rollers a shaft A is provided and eX- tends transverselyof the machine, having bearing-boxes A at opposite sides thereof, theupper roller B being mounted upon said shaft. The upper portion of thebearing-box A may be removable and held in position by means of a wedgeA which exerts the necessary pressure thereon and adjusts the relationof the dies toward each other, said wedge being adapted to contact witha fixed projection A from the ring and to be secured in position by aset-screw A The shaft A may be driven from any suitable connections, forinstance, by means of a worm-wheel A engaging a 5 worm-shaft A, havingatits outer free end a driving-pulley A of usual construction.

Any desired number of the die-rollers B may be provided and disposed atequal distances apart, so as to cover substantially the entire peripheryof the article to be ornamented, there being shown herein four of suchrollers disposed in pairs opposite to each other. The journals of thedie-rollers in the lower brackets A may be held in suitable relation toeach other by means of an angle-iron B mounted at the angle of thebracket and adjustably secured by means of a set-screw B. These rollersare each provided upon their shafts with bevel-gears 15* at the oppositesides thereof, said gears meshing with similar gears upon the adjacentrollers disposed at an angle thereto. hen the upper roller B is rotated,the gears at the opposite sides thereof mesh with the gears upon theupper face of the side rollers, thus driving those rollerssimultaneously in the same direction as the upper roller, while thebevel-gears upon the under face of the side rollers mesh withcorresponding gears upon the lower roller, thus carrying all of therollers and the dies thereon in the same direction to feed the workduring the ornamenting action.

For the purpose of supporting the dieblocks G, which may be of anydesired construction, size, or configuration necessary for the work tobe performed, a novel construction of chuck is illustrated in Fig. 3,the dies being there shown as provided with a concaved ornamented faceand with a dovetailed base C, adapted to be engaged by a corre spondingrecess upon the opposite slidable chucks which are mounted upon a sleeveC provided with a longitudinally-extending key (1, which permits areciprocation of the chuck members, while insuring their rotation withthe sleeve. At the opposite side of these chuck members the beveledgears B are mounted upon the sleeve and key, so as to retate these partswhen driven. For the purpose of adjusting the chuck members aninteriorly-threaded ring G is secured to each of the gears and rotatablethereon for instance,

by means of set-screws C, passing through apertures in the gears andentering a circumferential groove in the ring C Fig. 5. T he ring isalso provided with a series of wrench-holes C to permit the applicationthereto of a spanner-wrench interposed between the gear and chuck,whereby the rings may be rotated for the purpose of adjusting the chuckstoward and from each other, and thereby clamping or releasing the dies(3, carried by the chucks. As shown in Fig. 1, the material D to beornamented is introduced between the dies at their point ofintersection, so that the ornamenting-surfaces cover substantially theentire periphery of the work and produce thereon a radial pressuretoward the center thereof and a pressure tangential to the center uponlines parallel and radial, such tangential lines intersecting each otherto produce a resultant radial pressure toward the center, as if theentire periphery of the work were compressed radially.

In the operation of the machine the material D is introduced between therotating dies and is fed by them while being ornamented by thecompression hereinbefore described, so that all of the periphery of thematerial D is simultaneously engaged by the dies, and

l l l owing to the resultant radial compression toward the centerthereof any splitting of the Wood or material is prevented, while eachof the dies resists the pressure of its opposite member and by theirjoint action produce an ornamentation of equal depth upon all theperiphery during a single operation of the machine.

The construction of frame .here disclosed provides a rigid, simple, andefficient means for mounting the assemblage of dies illustrated, whilethe construction of chuck permits these dies to be removed and replacedwithout difliculty by the simple use of a wrench and withoutdisconnecting any of the driving parts of the apparatus. It also permitsthe use of large gears by which a direct meshing between the die-rollersis secured, thus eflecting the necessary simultaneous operation of eachof the dies and requiring the minimum of power to effect the same.

It will be obvious that changes may be made in the details ofconstruction and configuration without departing from the spirit of theinvention as defined by the appended claims.

Having described our invention and set forth its merits, what we claim,and desire to secure by Letters Patent, is

1. In an ornamenting apparatus, a plurality of dies disposed atequidistant points to embrace substantially equal portions ofpractically the entire periphery of an article, and means for rotatingsaid dies simultaneously in the same direction to effect a radial andtangential pressure toward the center of the work, the tangential linesof pressure from one die intersecting those from another to produce aresultant radial compression toward the center of an article.
